Incoming data is modem 3 of industrial equipment S
Is demodulated by the data communication device 12 and output to the control and monitoring device 2, so that the control and monitoring device 2 can confirm that the report data has been transmitted to the dedicated management device 4.

Further, at every predetermined time (periodically), a list (report report data) of the stored report data is formed, and this list is printed by the printer 27, and at the same time, the report report data is output to the data communication device 20. The report report data is encoded by the data communication device 20, transmitted to the modem 8 of the computer 9 through the NCU 19 and the public line 1, demodulated by the modem 8, and stored in the computer 9.

When the input data is collected data, the control device 21 forms a stored collected data list (collected report data) at predetermined time intervals (periodically), and prints this list by the printer 27. At the same time, it outputs the collected report data to the data communication device 20. The collected report data is encoded by the data communication device 20, transmitted to the modem 8 of the computer 9 via the NCU 19 and the public line 1, demodulated by the modem 8, and stored in the computer 9.

When it is confirmed that the collected data has not been transmitted at a regular time, the non-arrival data indicating that the transmitted data has not arrived is output to the data communication device 20.
The non-arriving data is encoded by the data communication device 20 and transmitted to the modem 3 of the industrial facility S notified via the NCU 19 and the public line 1. The unreceived data is demodulated by the data communication device 12 of the modem 3 of the industrial facility S,
Output to the control monitoring device 2, the control monitoring device 2 confirms that the collected data is not transmitted to the dedicated management device 4,
Actions such as resending the collected data can be taken.

As described above, by providing the dedicated management device 4, each industrial facility S is provided with a notification means (a voice data exchange 22, a paper format exchange 23,
It is not necessary to provide the voice communication device 24, the DTMF transmission device 25, and the facsimile communication device 26), and the cost as a remote monitoring facility can be reduced.
